Study Notes
Introduction to Ordering Fractions
- Ordering fractions, especially those with different denominators, needs a structured method to compare their values precisely.
- Visual models effectively aid in intuitive understanding and ordering of fractions.
Models for Ordering Dissimilar Fractions
-
Number Line Model: A number line visually represents the magnitude of numbers. Placing fractions on the number line simplifies comparing their relative positions and values.
- Identify the endpoints or boundaries of the fraction's range.
- Mark the position of the fractions on the line.
- Arrange the fractions in ascending or descending order based on their positions on the number line.
-
Area Model (Rectangles): Dividing rectangles into equal parts visually represents fractional parts.
- Draw rectangles of equal size.
- Divide each rectangle based on the denominator of each fraction.
- Shade the appropriate sections to represent the numerators.
- Compare the shaded areas to determine the larger fractions.
-
Fraction Circles: A set of fraction circles representing different unit fractions facilitates visual comparisons.
- Select circles corresponding to each fraction.
- Note the number of equal slices in each circle.
- Shade the sectors representing the numerators.
- Visually compare the shaded sector sizes to order the fractions.
Ordering Steps Using Models
-
Step-by-Step Process for Ordering Fractions: Use the chosen model to visually represent the fractional values.
-
Identify Denominators: If the fractions have different denominators, find a common denominator by determining the least common multiple (LCM) of their denominators.
-
Convert to Equivalent Fractions: Change the fractions into equivalent ones, each with the same denominator.
-
Compare Numerators: Once the fractions have the same denominator, their order is determined by comparing the numerators.
Examples using Models
-
Example 1: Ordering (1/2), (2/3), and (3/4): Use the area model to divide rectangles into halves, thirds, and fourths. Visualize equivalent fractions to compare and order.
-
Example 2: Ordering (3/5), (4/7), and (2/3): Use the number line to position the fractions. Compare the equivalent fractions and order them. Also use the fraction circles for clear visualization and comparison of different fractions.
Key Concepts
-
Visual Representation: Visual models (number lines, rectangles, fraction circles) show fractional values and their relative sizes.
-
Common Denominators: Changing fractions to have the same denominator simplifies comparing their values using numerators.
-
Order of Comparison of Numerators: After converting fractions to a common denominator, comparing their numerators directly gives their ordered arrangement (least to greatest or greatest to least).
